OUTER RING ROTATING SEALING TYPE ROLLING BEARING

摘要

PROBLEM TO BE SOLVED: To securely and uniformly feed a lubricating oil to each row of rolling elements even if a pressure loss difference is present in a bearing. SOLUTION: This sealing type rolling bearing 1 feeds and discharges the lubricating oil from the side of a shaft fitted to an inner ring 2 into the bearing. Since an oil supply passage 20 and an oil discharge passage 21 are formed on each of the axial one side and the other side of the inner ring 2, the lubricating oil is fed from the axial one side of the inner ring 2 and discharged from the other side.
